Fig. 3

Two-dimensional crustal deformation calculated from the slant-range changes for Paths 28 and 126. Thin lines depict the surface ruptures associated with the 2016 Kumamoto Earthquake (Awata et al. 2019; National Institute of Advanced Industrial Science and Technology 2019). a Quasi-east–west (QEW) component of crustal deformation. The quasi-east direction is rotated 3 degrees clockwise from the east. The two boxes correspond to the areas of (d and g), respectively. Shaded areas show the caldera wall. b Quasi-up–down (QUD) component of crustal deformation. The quasi-up direction inclines 8 degrees northward from the vertical. The two boxes correspond to the areas in (e and h), respectively. c Topographic relief map. (d, e) Distribution of the QEW and QUD components, respectively, enlarged west of the Aso Caldera, corresponding to Fig. 1c. f Vertical displacement along the profile A–A' shown in (e). (g, h) Distribution of the QEW and QUD components, respectively, enlarged around the Futagawa Fault, corresponding to Fig. 1d
